A clamp for securing together in locked relationship a pair of telescoped pipes or tubes. The clamp consists of a novel U-bolt having a swaged flat rim on the inner portion of its bight which reduces the radius of the bight portion, and a novel saddle member having a semicircular cut-out and being further chamfered adjacent the ends of the semicircular cut-out to define a greater diameter. The assembly when in its loading position will accept a pipe joint of greater outside diameter than the inner diameter of the tightened clamp; and wherein tightening of the clamp initially deforms the pipe joint into an ovaled configuration and subsequently returns it to a circular configuration and impresses a bead thereabout for 360°.

In a clamp for sealing and interlocking telescoped metal tubes or the like to each other, said clamp comprising a U-bolt having a pair of parallel, spaced legs, said legs having threaded ends, and a semicircular bight portion located between and interconnecting said legs, a saddle member having a pair of spaced tubular parallel housings adapted to receive said U-bolt legs, and nut means adapted to thread onto the ends of said legs to move said saddle member toward said bight portion, the improvement comprising said bight portion of the U-bolt being provided on its inner face between said legs with contact means extending for more than 180°and extending inwardly towards the bight center and adapted to contact the outer of said telescoped metal tubes, said saddle being formed of a pair of substantially identical planar sheet metal webs welded together in face-to-face contact and having an arcuate cut-out portion of less than 180°extending between said housings, the ends of the cut-out portion being chamfered outwardly to provide a large mouth opening, wherein a pair of metal tubes having an outside diameter that is greater than the inside diameter of the clamp when completely tightened about the telescoped tubes may be received by virtue of the opening between the U-bolt legs and the chamfered ends of the cut-out portion, said cut-out portion having means thereon cooperating with said contact means when the clamp is in its completely tightened condition to provide a continuous uniform circumferential bead on said telescoped tubes.
